The Equinoxe Resurfacing Humeral Head System is indicated for use in skeletally mature individuals with degenerative diseases of the glenohumeral joint where hemi- or total arthroplasty is determined by the surgeon to be the preferred method of treatment. The Equinoxe Resurfacing Humeral Head System is intended for use in patients with the following conditions where the humeral head and neck are of sufficient bone stock and the rotator cuff is intact or reconstructable.
- Osteoarthritis .
- Avascular Necrosis .
- Rheumatoid Arthritis
- Post-traumatic Arthritis .
- Correction of functional deformity 0
- Fractures of the humeral head 0
The Equinoxe Resurfacing Humeral Head System is intended for uncemented use only.
The Equinoxe Resurfacing Humeral Head System is intended as a cementless humeral resurfacing system that can be used in hemi- shoulder arthroplasty (where it does not articulate with a glenoid component) or total shoulder arthroplasty (where it articulates with a glenoid component). Implantation of this device involves minimal bone removal. The overall design goal of the Equinoxe Resurfacing Humeral Head System is to provide a bone-preserving option for treating degenerative conditions of the shoulder joint.
The Equinoxe Resurfacing Humeral Head System is a modular system, consisting of an articular humeral head component and a humeral cage component mated together via Morse taper connection to provide stabilization of the implant assembly. The dome shaped resurfacing humeral head component is manufactured from cobalt-28Chromium-6Molybdenum alloy per ASTM F1537 with titanium plasma coating per ASTM F1580 and Hydroxylapatite coating per ASTM F1185 on the non-articulating or bone-contacting surface. Manufactured from titanium alloy (Ti-6Al-4V ELI per ASTM F136) with titanium plasma coating per ASTM F1580, the cylindrical cage component features multiple fins for anti-rotation. The variable sizing options and the modular composition of the Equinoxe Resurfacing Humeral Head System facilitates selection and anatomic reconstruction of the native humeral head.
If utilized in total shoulder arthroplasty procedures, the System is compatible with the following Equinoxe Shoulder Glenoid components: Keeled Glenoids, Pegged Glenoids, Caged Glenoids, and Augmented Glenoids cleared with the following 510(k)s: K042021, K093430, K113309, K103419, K111379, and K121220.
The Equinoxe Resurfacing Humeral Head System is accompanied by a complete instrumentation and trial system to assist the surgeon in the implantation of each component.

§ 888.3690 Shoulder joint humeral (hemi-shoulder) metallic uncemented prosthesis.
(a)
Identification. A shoulder joint humeral (hemi-shoulder) metallic uncemented prosthesis is a device made of alloys, such as cobalt-chromium-molybdenum. It has an intramedullary stem and is intended to be implanted to replace the articular surface of the proximal end of the humerus and to be fixed without bone cement (§ 888.3027). This device is not intended for biological fixation.(b)
Classification. Class II.
